NoClassDefFoundError - ApplicationContextAware
Last night I (unsuccessfully) attempted to set up a simple
Struts 2 web app. I am absolutely sure that all the JAR
files are in the correct /WEB-INF/lib directory. The
error appears to be happening because it cannot find the
Spring interface ApplicationContextAware. I would think
that if Struts 2 had any dependencies on this interface,
it would include them in its own JARs, and not require the
user to go download the Spring framework during normal
installation. I am using Eclipse 3.2, Tomcat v5.5, and
have tried using both JDK 5 and 6.
Here is my struts.xml (I have also tried it using dummy
action entries)
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts
Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
</struts>
Here is my web.xml

Please help!
Sincerely,

P.S. The only help I could find on this problem is a post
in another forum written in what I think is Mandarin
Chinese:

If you are going to use Spring as your object factory
then you will need to download Spring; S2 provides a
*plugin* for Spring integration, but not Spring
itself.
This makes sense if for no other reason than Spring is
big, and you should be able to pick and choose which
Spring components you want rather than create a
dependency on the entire Spring distro.
S2 doesn't "depend" on Spring unless you tell it to
(or, perhaps in this case, someone told it for you).
